Definitions
- the invention relates to a quench cooler for cooling a hot flowing gas, consisting essentially of a cylindrical jacket, which has a gas inlet connection with a hot gas line and via a gas outlet connection is connected to a cold gas line, and which one Has means for injecting water. It also affects the use of such a quench cooler in an open Gas turbine plant.
- a quench cooler for cooling hot flowing gases known for example from EP 0 647 462 A1.
- This cooler consists of a cylindrical jacket, which over a Gas inlet connection with a hot gas line and over one Gas outlet connection is connected to a cold gas line and what means to inject water and downstream has a filling for mixing the two phases.
- the water injected by a pump through nozzles forms relatively large drops, which causes thermal contact is relatively small and mainly in the field of subsequent filling remains limited.
- the invention is therefore based on the object Quench cooler with high efficiency for high gas and liquid temperatures and create high pressures.
- the special one thermohydraulic requirement for this class of Apparatus, provided that it is used in modern gas turbine systems Application is as follows: high gas inlet temperature between 300-530 ° C, high pressure on the gas side between 20 and 35 bar, low gas and liquid side Pressure losses and relatively high cooling span of the gas larger than 250 ° C.
- this object is achieved in that the Water injectors are pressure atomizing nozzles, which with Water and water vapor are applied and that was needed to atomize the water Water vapor is generated in an evaporator, which in the Hot gas line itself is arranged.
- the advantage of this The measure is particularly to be seen in the fact that the separate Provision of the commonly used atomizing air can be dispensed with.
- FIG. 1 becomes atmospheric in the gas turbine cycle at 1 fresh air drawn in in a compressor 2 on the Compressed working pressure.
- the compressed air is in one for example, combustion chamber 3 fired with natural gas heated; the resulting fuel gas is in a gas turbine 4 relaxed while working.
- the energy gained is delivered to a generator 5 or the compressor 2.
- the Exhaust gases from the gas turbine are via the exhaust line 6 and a chimney, not shown, led outside.
- the compressor 2 For the air used for cooling purposes branches from the outlet the compressor 2 has an air line 7 to a quench cooler 8 from. After it has flowed through, the cooled air arrives via a cooling line 9 to the various consumers. On the water side, the quench cooler is connected via line 22 fed a water pump 15.
- This quench cooler 8 is explained in more detail with reference to FIG. 2: Via the hot gas line 7 - here the air line from the Compressor - the medium to be cooled gets into the apparatus.
- the apparatus essentially consists of the gas inlet connection 11, which on the one hand flanged to the air line 7 and on the other hand via a flange with the cylindrical Jacket 10 is connected. This is on the outlet side Jacket 10 in turn via a flange with the gas outlet connection 12 connected, which also on the cold gas line 9 - here the cooling line - is flanged.
- the water injection means arranged. This is about it is a plurality of pressure atomizing nozzles 30. You become on the one hand from an annular chamber surrounding the apparatus 20 fed with water, on the other hand with steam from one ring apparatus 21 surrounding the apparatus. The steam is used for Atomization of the water, droplets in at the nozzle outlet Micron size can be achieved.
- the flow through is downstream of the pressure atomizing nozzles 30 circular cross section of the jacket 10 with a static Mixer in the form of a packed column 13 provided.
- a such a cylindrical column 13 contains layered packing, hereinafter referred to as the pack. It can be a Act bulk, so a so-called disordered filling (random packing). An orderly one is more suitable Filling (regular packing), which has the advantages of a higher Mixing performance with lower pressure drop due to homogeneous offers targeted distribution.
- regular packing regular packing
- As material for such in itself known packs can use stainless steel or ceramic which are all characterized by good wettability in aqueous Systems.
- the injected water and air flow through the several Regular packing layers in DC.
- the pack finds complete mixing of the two phases instead, the water portion evaporates.
- the hot air provides the enthalpy of vaporization so that an isenthalpic
- the air temperature in the apparatus is reduced.
- Es is understood that in connection with the numerical values mentioned with regard to the dimensioning of the apparatus and in particular the required pack length on the indication absolute values must be dispensed with because these values are due to their dependence on too many parameters are not sufficiently meaningful anyway. Decisive for the design is only that a complete evaporation of the injected takes place.
- the entry state of the air to be cooled is approx. 34 bar and about 500 ° C; the air volume is approx. 35 kg / sec.
- the injected The amount of water is approx. 10 kg / s.
- the work equipment leaves the apparatus then as cooling air with a temperature of approx. 170 ° C. In the present In this case, the air is cooled down by 330 ° C.
- Such an apparatus is characterized by a compact design and works without significant pressure drops.
- the Compactness and the only short cables required allow the quench cooler to be installed immediately Close to the machine, so that it can be used for sound insulation of the thermal block can be included.
- the performance of the gas turbine thereby increased that the mass flow acting on the gas turbine at least partially by the amount of water evaporated is increased; After performing its cooling function, it will Coolant namely for the work performance in the gas turbine blading further used.
- the pack is in its own casing in the column 14 held in the form of a thin sheet and thus as in the cylindrical shell 10 insertable cartridge.
- This has the advantage that there are no evaporation residues can settle on the actual apparatus jacket 10.
- At the Removal of the column for the maintenance remains one Evaporation residues forming within the layer Cartridge. The risk of particles breaking off the jacket wall 10 and their possible transport in the to be cooled This eliminates consumers.
- a cooling air flow leading into the hot part of the gas turbine must not contain any water droplets as they hit them damage to the hot parts. If water is detected in the cooling air flow, must the machine can be turned off.
- Water detection agent for the present high pressure and temperature conditions in modern gas turbines are not currently available on the market.
- the remedy here is a temperature measurement in static Mixer itself, for which a number of corresponding switched thermocouples 25 arranged inside the package are. Just like water on the walls of the packing crashes, their temperature drops quickly. When the water flow is large enough, the temperature of the pack will be up decrease to wet steam temperature. Such a measurement is therefore suitable to detect water in the shortest possible time, which strikes the packing.
- thermocouples 26 and 27 Another method to determine the presence of water as well Checking evaporation in the column consists of one Temperature measurement upstream and downstream of the static Mixer. For this purpose, appropriate thermocouples 26 and 27 passed in a suitable manner through the jacket 10 and adequately distributed in the flow-through cross-section. The finding a temperature difference between entry and exit the mixer indicates proper evaporation there.
